OTE is how electricity is generated from the solar energy absorbed and stored in the tropical oceans.

A large floating vessel similar to an ocean drilling rig houses the power cycle.

Warm 80 degrees F surface water is pumped through heat exchangers in order to boil a working fluid into vapor under pressure at 67 degrees F. The vapor then expands through vapor turbines which drive generators.

Cold 40 degrees F water is pumped up from 4,000 feet below the surface to condense the vapor back into its liquid state. The cold liquid working fluid returns to the evaporators where the liquid is heated and boiled all over again. Read

Although Ocean Thermal Energy Conversion has a long and interesting history, it was J. Hilbert Anderson and his son, James H. Anderson Jr., founders of Sea Solar Power, Inc., who first showed how to design and build such plants economically. Prior to beginning an exhaustive study of OTEC in 1962, Hilbert Anderson had extensive experience designing refrigeration and heat power cycles. Read

Compared to the most dramatic American engineering achievements of the last century, such as putting a man on the moon or building the atomic bomb, OTEC is clearly well within our capability and ingenuity. We believe its implementation will be comparable to the dawn of “big oil”, our fuel of choice for the last 100 years. As OTEC technology further matures, costs will continue to drop. Read

Sea Solar Power, Inc., through private funding, has continued to develop and test the key elements of a Rankine cycle OTEC plant. These are vapor turbines, water pumps, heat exchangers, the cold water pipe, the vacuum pump, and the integrated floating structure. Excellent progress has been made. Read

Our modern global community is confronted with
a multitude of challenging environmental problems.
Global warming possibly fueled by consumption of fossil fuels, may be threatening man and the Earth's very survival.

In 1962, Hilbert and son James Jr. started working on the concept of sea thermal power, (ocean thermal energy). Jim Jr. wrote his mechanical engineering BS thesis at MIT on an application of a sea thermal power plant... Read More...
